Infectious medical waste refers to all types of infectious, pathological, injurious, pharmaceutical, or chemical waste generated by medical institutions in medical, preventive, health care, and other related activities. These wastes contain large amounts of bacteria or viruses and are characterized by space contamination, acute viral transmission and latent infection. Medical test reports from the national health department show that the viruses and bacteria in medical waste are tens, hundreds or even thousands of times more harmful than ordinary household waste. If discarded or improperly disposed, allowed to be mixed with ordinary household waste and dispersed into the people's living environment, it will not only pollute the atmosphere, water, soil, animals and plants, but also may become a secondary source of epidemic disease.
Therefore, the reasonable and safe disposal of infectious medical waste is of great significance to protect the ecological environment and safeguard public health. How to collect and dispose of these medical wastes is a much-needed part of the process of fighting the epidemic.The first step in the safe disposal of collected infectious medical waste lies in sorting and segregation. After the waste is transported to a centralized treatment facility, it will eventually be destroyed harmlessly through three types of mainstream thermal disposal methods: high, medium and low temperature. Among them, incineration and steam autoclave treatment are the two most common medical waste disposal processes.
High-temperature incineration disposal processes are typically performed at temperatures above 850°C, resulting in complete destruction of the waste and a significant reduction in the mass and volume of the waste. Incineration is the most common process for high-temperature thermal disposal of waste. Its advantage is that it is suitable for the disposal of almost all types of hazardous medical waste, especially chemotherapy waste, pathology waste, tissues and organs, etc. This method can significantly reduce the volume and weight of the waste. Also, incineration is considered to be the safest method of disposal for infectious medical waste because high temperatures can destroy 100% of bacteria and viruses.
However, incineration of medical waste produces a variety of gaseous pollutants, including dioxins and furans, metals (e.g., lead, mercury, and cadmium), particulate matter, acid gases (hydrogen chloride and sulfur dioxide), carbon monoxide, and nitrogen oxides. Emissions of these pollutants can have serious adverse consequences for operator safety, public health and the natural environment. Therefore, incineration processes need to be accompanied by efficient exhaust gas treatment processes to minimize the risk of secondary environmental pollution from exhaust gas emissions. The recent haze and high concentrations of air pollutants observed in some cities are most likely related to the incineration of medical and health care waste.
The pyrolysis-incineration disposal process is carried out at temperatures between 850-1100°C and requires chemical agents for the decomposition of inorganic components. The most representative thermal disposal process. This process uses high energy heat to decompose medical waste directly in a nitrogen atmosphere. It produces charcoal, natural gas, and high energy fuel. The natural gas and high energy fuel are recycled to the pyrolysis kettle by incineration in a second combustion chamber. This process can be widely used to treat various infectious medical wastes such as biological and anatomical wastes, needles, knives, plastics, and glass, etc. The emissions are dioxin-free and meet natural gas emission standards.
